There a lots and lots of different ECUs. What do you need to know? Depending on the year of your car, CD or not, engine size, turbo or non-turbo, you may have LH 2.2 injection and APC or LH 2.4.2 injection and DI/APC or Trionic or Motronic. For each of these alternatives there is a number of different part numbers to suit the different engine variations.

In the case of DI/APC cars, there are separate ECU programs for fuel (LH injection ECU) and ignition/turbo (DI/APC ECU).

tertsi, your LH ECU part number is 93 88 471. I see no other part number for '85. You are correct that the APC is separate.
APC is 75 21 818 without catalytic converter, 75 23 970 with cat.

What exactly do you need to know?
